I don't get this.. It should be working, but that is impossible.. Please explain

>> No.3032734

It takes too much force to force the bottom ball into the water. The force of the rising balls (actually they don't all pull together; you get only the force of one rising ball) is not enough to push the ball down through the flap into the water.

Why do you think the left side would be heavy enough to turn the whole apparatus?

People always come up with these stupid ass perpetual motion machines and NONE of them even look like they would be plausible.

>> No.3032776

>>3032757
the bouyancy on the right side produces far more force, its just that in order for water not to seep out, the seal at the bottom must be very tight, and so all that momentum is lost trying to fit the next ball in.

so what if you make the part with air in an L-shape, so none of the balls have to go downwards into the water

I assume you're replying to me.

I'm looking at the picture, there's nothing intuitive about it. The whole thing looks like it would be stationary.

>>3032817
nope.
all that water weight is pushing down on the valve, the valve must be firm enough to stop any waterleak for this to be a usable system. in order for a ball to move into the right side of the chamber, it must push through all of that water weight to make a gap in the seal for it to fit through. this cancels out all the extra momentum that you would have gained by the bouyancy it experiences when it actually gets into the right hand side of the tank.

I just drew this.. tell me why it wouldnt work.

These workers are from china and they are getting payed 10 cents an hour.

1 group pulls on the rope than once they run out of slack then there is a little runner boy who pulls the slack out on the other side.

The rope is attached to the windmills by like a gear or idk they just pull spin the turbine somehow.

Can windmills go forward and backwards ? Will that still generate electricity? I would think it would like reverse the magnetism or whatever... Let me know.

I'm going to guess that burning the workers' bodies for fuel would be much, much more efficient. There's a reason nobody is doing that.

>> No.3033042

>>3033027
yes it would work.
just as wind turbines produce electricity when powered by the wind, they will do the same when powered by small chinese children.

>> No.3033058

>>3032970

I don't get it. Why are there windmills? Why not just have all those Chinese people turning a crank directly? Or put them on exercise bicycles?

I mean, yes, you can generate electricity with human muscles, but there are much, much easier ways to do it.

>> No.3033070

>>3033033
Hey, I mean...

Lets say there is only 1 turbine and 2 people...
I am paying them chinese minimum wage. Or even africa... Whatever it is...

If that process is profitable even in the slightest like 10 cents an hour after paying wages... you could theoretically just make thousands of these. If you could handle that big of a operation and have a lot of money to start off.

Well the idea first was to make it use like a pulley to reduce the effort but idk.

Heres another idea... once they pull it all the way up the rock does the other half of the work by itself because gravity...

>> No.3033096

>>3033080

It still doesn't make any sense to be turning windmills.

And the rock isn't "doing half the work" because it takes more energy to lift it up then you get out by letting it down.

There is multiple wind mills that the workers are turning.

Its not , 1 person per bike.

Its a bunch of people pulling multiple turbines and sharing the effort. They wont get tired as fast and it will produce a lot more energy.

Source.

How is this not more efficient than bike power?

You could have 10 workers pulling 30 wind mills.. With bikes you only have 1 bike per person.

Im not even concerned about how much their muscles hurt because if they get tired I could instantly swap out that particular worker for a new one.
